To all w/tom it 11mg concern.- i

Be it known that we, CHARLES TRENCHE VENT DE S'r. AUBIN and ARUHIBALD Y. Con- STOCK, both of New York city, in the county 5 and State of New York, have invented anew andlmprovcd Apparatus for Feeding ()il t Burners, of which the following is a full, clear, and exact description.

'Our invention relates to an apparatus for to feeding oil to burners, and the especial ob ject of the invention is to force oil or other liquid fuel of less specific gravity thanwaterwith 'auniform pressure from arcceptacle V buried at any desired depth below the surface of-the ground, and'loeated'at any distance The invention consists in the novel construction and combination of the several 20 parts, as will be hereinafter fully set forth,

and pointed out in the claim.

Reference is to be had to the accompanying drawing, forming a; part of this specification, which represents a side elevation of the ap- 2 paratus, partly in section.

A'reeeptaclc 10, adapted to receive petro- 'lcum or other liquid fuel, may be located at any desired point, preferably below the surface of the ground and at a distance from 30 the boiler 11, or the machine or apparatus to which the fuel is to be fed. The receptacle is provided at one side with a gageglass 12, of any desired construction, and at the bottom with a waste-pipe 13, connected with a sewer 5 or drain it, said waste-pipe being provided with a stop-cock 15. From the top of the receptacle tn o tubes 16. and 17 are carried upward, each provided with a suitable valve 18, one tube serving as a medium for the intro- 0 duction of the oil into the receptacle and the other tube acting as a vent.-

The supply-tube if) of the burner :20 is litted with a valve 21 and is connected in any suitable or approved manner with the top of 5 the oil or fuel receptacle.

At any desired point above the surface of the ground a waterehambcr 22 is constructed, preferably provided with an open top and having a pipe-connection 23 with the bottom so of the oil or fuel receptacle 10, which connection is furnished with a valve 24, located u fromthe-place"-ot'boinbustion, regardless of 1 said depth or said'distance.

ordinarily immediately beneath thereceptacle. The water-service pipe is carried upward and curved over the top of the Waterchambcr 22, being provided ordinarily with two stop-cocks a and a, and through the handie of the upper cock a. the stem of an airtight float 26, located in the water-chamber, is passed, which stem is adj ustably connected with the said coclc a, the connection being usually efiected by threading the upper end of the stem and screwing nuts 27 thereon, one located above and the other below the handle of the upper cock, as illustrated. A waste-pipe 538 is located at the side of the water-chamber and connected at its lower end with the drain or" sewer, and a series ofi tubes 29, arranged one above the othetflis preferably utilized to connect the wastepipe 28 and the water-chamber, each tube beingjc fitted with a stop-cock 30. To fill the receptacle 10 with oil-or other liquid fuel, the Valves 15, 21, and 2st and the stopcock a are closed and the valves 18 int the supply and vent pipes 16 and 17 are opened. The oil or fuel is thereupon poured into the supplypipe 16, the air or gases findingan escape through the vent-tube 17. The height of the oil in the receptacle may be do termined through the medium of the gage- 8:; glass 12, and when the receptacle has been properly filled the valves 18 are closed and the valve 2% and stop-cock a opened, thus allowing the water from the chamber 22 to flow through the pipes 23 into the receptacle 10 at the bottonrand bclowthe liquid fuel, and the said fuel; by reason of the pressure of the water-cblumn, is forced through the .pipe I 19 and valve 21, which is now opemand com bustion will take place at the burner 20. go

The air-tight float 26 serves to cut off the supply of water from the service-pipe 25 when the height of the column of Water de sired is obtained in the water-chamber 22. The height of the column of water is reg'w lated by opening at will either of the stopv cocks 30, which serves as an overflow, through the medium of the waste-pipe 28 to the drain pipe or sewer 14. The float israised or low cred to suit the level of the water or press-.100 urc desired in the wa ter-chamber 22 by ma" nipulation of the nuts 27, whereby the stem I of the heat may be raised or lowered. The

" level or pressure is controlled by opening" fuel-supply from the burner supply-pipes,

, 15of thewaste-pipe w opened, thuscutting the stopcock a is closed and the stop-cock 01f the supply of water from the SGI'VlOGvPiPQ 25 andv allowing the water to escape from the receptacle into the drain or sewer 14. When the upper surface of the oil is visible through the gage-glass 12, the stop-cock is closed.

We are aware that the method of. feeding oil or similar fluid fuel to a burner consisting in forcing the oil upward by a column of heavier fiuid is not new, or the employment of petcocks or valves to regulate the Weight of the columns of the heavier fluid, and We do not, therefore, claim the same as our invention.

Having thus described our invention, we claim as new and desire to secureby Letters Patentsenses drain, a series of valved horizontal waste-v tubes connecting the vertical waste-tube and stand-pipe, said horizontal tubes being arranged one above the other, a-serviee-pipe provided with stop-cocks and having an out let in the stand-pipe, and a float located in the stand-pipe adjustably connectedwith one of the stop-cocks of the service-pipe, all com-- bined for operation substantially as specified.
